DOUBLE-SIDED PRINTING AND BINDING OF BOOK HARDCOVERS

摘要

A process for double-sided printing of a book hardcover, which includes: providing a book hardcover having a spine between front and back covers all integrally formed from a single blank of foldable board material, wherein the front and back covers each have polymer coated inside and outside surfaces; providing inside and outside dye sublimation sheets respectively printed with inside and outside front and back cover images using dye sublimation ink; superposing the inside and outside dye sublimation sheets respectively on the inside and outside surfaces of the front and back covers when the book hardcover is open flat; applying heat and pressure to the superposed inside and outside dye sublimation sheets and inside and outside surfaces of the front and back covers to respectively sublimate the dye sublimation ink of the inside and outside front and back cover images into the polymer coatings on the inside and outside surfaces of the front and back covers to thereby form a double-sided printed book hardcover.
